Abstract

A system for automatically controlling intrusion thresholds of intrusion detectors deployed in a premises, the system including intrusion detector output receiving functionality operative to receive at least one output from at least a first intrusion detector deployed in the premises, intrusion detector output comparison functionality operative to compare the at least one output from the at least a first intrusion detector with at least one of a multiplicity of premises intrusion detection patterns, and intrusion detector threshold controlling functionality operative, in response to ascertaining that the at least one output from the at least a first intrusion detector matches at least one of the multiplicity of premises intrusion detection patterns, to automatically tune a threshold of at least a second intrusion detector deployed in the premises.

Claims

1. A tunable intrusion shock detector comprising:

at least one sensor having a tunable intrusion threshold;

discrete intrusion threshold tuning functionality operable for at least one of local and remote discrete tuning of an intrusion threshold of said intrusion detector to one of at least three discrete precalibrated threshold levels, each of said at least three discrete precalibrated threshold levels being represented by a discrete numeric value; and

a transceiver operable for at least one of remotely transmitting and remotely receiving said intrusion threshold of said tunable intrusion shock detector, said transceiver being operable for at least one of transmitting and receiving said intrusion threshold of said tunable intrusion shock detector between said tunable intrusion shock detector and at least one of a system for automatically controlling intrusion thresholds of tunable intrusion shock detectors deployed in a premises and a system for automatically remotely controlling intrusion thresholds of tunable intrusion shock detectors deployed in a plurality of premises.

2. A tunable intrusion shock detector according to claim 1 and also comprising discrete intrusion threshold input functionality communicating with said discrete intrusion threshold tuning functionality, operable for manually tuning said intrusion threshold of said intrusion detector to one of said discrete precalibrated threshold levels.

3. A tunable intrusion shock detector according to claim 1 and wherein said discrete intrusion threshold tuning functionality comprises an alpha-numeric display operative to display said discrete numeric value representing said precalibrated intrusion threshold of said intrusion detector.

4. A tunable intrusion shock detector according to claim 2 and wherein said discrete intrusion threshold input functionality comprises at least one push button.

5. A tunable intrusion shock detector according to claim 1 and wherein each of said local and remote discrete tuning of said intrusion threshold of said intrusion detector comprises tuning said intrusion threshold to said discrete numeric value.

6. A tunable intrusion shock detector according to claim 5 and also comprising a memory operative to store said discrete numeric value.

7. A tunable intrusion shock detector according to claim 1 and also comprising a microphone for detection of at least one acoustic event which may be indicative of an intrusion.

8. A tunable intrusion shock detector according to claim 7 and also composing shock sensing functionality operative to sense shock waves and to employ said intrusion threshold stored in said memory to ascertain whether a combination of said sensed shock waves and said at least one acoustic event received by said microphone is indicative of an intrusion.

9. A tunable intrusion shock detector according to claim 8 and wherein upon ascertaining that said combination of said sensed shock waves and said at least one acoustic event received by said microphone is indicative of an intrusion, said intrusion detector is operative to transmit an indication of said intrusion to an alarm system communicating therewith.
